In last week's RF Report, I said that due to the leap-second being added to Universal Coordinated Time (UTC), the GPS_UTC_Offset field in the ATSC System Time Table would change to 13 seconds from 14 seconds.
Obviously, this was going the wrong direction. The correct setting for the "GPS_UTC_Offset" field is 15 seconds. The Web version of the newsletter was corrected soon after the RF Report went out by e-mail and readers alerted me to the error—Thank you! If you modified your ATSC STT based on last week's uncorrected RF Report article, please accept my apology and change it now to 15 seconds.
Your comments and story leads are always appreciated! Drop me a note at firstname.lastname@example.org
